Nattaya Cameron, left, 8, straightens a "Cat in the Hat" hat on the head of Shianne Pelescak, center, 8, as her friend Allison Hall, 8, dances with her during a celebration for Dr. Seuss' 114th birthday on Monday at the Andrew Carnegie Free Library and Music Hall in Carnegie. Families gathered at the event to read Dr. Seuss' classic "Green Eggs and Ham," eat some birthday cake, and take part in Seuss-related games and crafts. The three girls even made up their own Seuss-related game, a take on "Duck, Duck, Goose" that they called "Cat, Cat, Hat."
